IP CONVERGENCE & IMS
TECHNOLOGY FOR BUSINESS
Printer-friendly PDF version
With significantly increased air interface throughput offered by the 4G wireless networks, backhaul networks are migrating from traditional TDM (T1/E1) to Ethernet Backhaul (EBH). The replacement of T1/E1 backhaul by EBH backhaul offers a more efficient and cost effective solution, and provides a more “future proof” backhaul network. This new backhaul paradigm requires the service provider to have a thorough understanding of the EBH supporting technologies such as IP, Ethernet networking, VLANs, etc. This workshop provides the necessary background for each of these technologies and through hands-on exercises demonstrates how the technologies are applied in the EBH network. The student will learn the basic IP, Ethernet and VLAN concepts (routing, protocols, addressing, EVCs, and tools, then apply these in a series of hands-on labs using a simulated EBH network. These labs will enable the student to apply the concepts, by building their own EBH network modeled after a real world wireless Ethernet Backhaul network. Though an end-to-end view will be presented, the workshop will focus on a cell site view of EBH.
After completing this workshop, the student will be able to:
• Read and explain the Configuration file on a router.
• Isolate and troubleshoot simple Ethernet and IP issues.
• Sketch a typical Ethernet Backhaul (EBH) architecture to meet 3G/4G backhaul challenges.
• Describe how signaling, user and management traffic flows through the EBH network.
• Sketch the VLANs in the EBH and their mapping to EVCs.
• Configure Ethernet VLANs and OSPF based IP networks.
• Use a network analyzer to trace packet flows through the network.
• Trace an packet flow through the various VLANs and IP subnets that make up the 4G backhaul network.
• Describe how Ethernet and IP nodes provide resiliency to faults in the 4G EBH.
• Estimate the number of IP addresses and subnets used by the 4G backhaul platforms and formulate an IP addressing scheme.
This workshop is intended for those familiar with the 2G/3G TDM backhaul, but are relatively new to Ethernet backhaul and an all IP RAN. It is a compact IP workshop for those who work on the wireless backhaul.
